Description

Comparative analysis of cell types across species (mouse, marmoset, macaque, human) to identify conserved vs species-specific cell populations. Includes ANTIPODE, mapping algorithms, and evolutionary divergence of cell-type transcriptomics. | Gap: No gold-standard metric for cell type homology; human-specific cell types have unclear functional analogs in model organisms.
